To all whom it may concern:

Be it known that I, FRANK O. MOBURG, a citizen of the United States, residing at Omaha, county of Douglas, and State of Nebraska, have invented certain new and useful Improvements in A paratus for Boiling Lime and Sulfur, of W ich the following is a specification.

My invention pertains to an afpparatus for boiling lime and sulfur, and has or its object an apparatus `of this type which will permit of the maximum amount of sulfur being put into solution with lime in water.

Other objects of the invention will appear in the course of the following specification. l

Referring to the accompanying drawings, wherein like characters of reference denote similar parts throughout the several views Figure 1, is a central vertical section of the ap aratus, Fig. 2, is a top plan view of the bo1 ing vat, and Fig. 3, is an enlarged detail being a cross section on line 3**3 of Fig. 1.

The apparatus comprises a boiling vat, A, shown arbitrarily in the drawings as of cylindrical form, which on its interior at points slightly above its bottom is provided with a plurality of steam cross pipes 2, each connected to a transverse feed pipe 3. Feed pipe 3, is secured by a union 3", to the lower end of a vertical depending steam supply pipe l, which latter enters vat A, from the central top portion thereof.

Byreference to Fig. 2, it will be observed pipe 3, is composed of a plurality of short sections a, a, a, a, eachof the same connected together by the couplings 5, whicl: latter have also the cross pipes 2, secured therete, and further a plurality of short sections 4, 4,A 4 4, of less diameter than that of sections a. I Thus it will be observed that the feed pipe 3, decreases in diameter towards its ends, which are farthest from the point of connection ofthe sup ly pipel, the purpose of which 1s to equa 1ze the steam pressure throughout the lengthV of feed pipe 3, to obtain as far as possible a uniform and equal distribution of the steam pressure throughout the area of the boiler vat, which latter is-secured by reason of cross pipes 2, being connectedto feed pi e 3. The equal and uniform distribution o the steam pressure is of vital importance since on the same depends the thorough and uniform agitation and boiling of the lime and sulfur solution at points in like manner. The cross` ipes 2, are all of the same diameter, each elng Specification of Letters Patent.

steam onto the bottom of vatA,

closed by'a cap ilatits outer end, and each l beingformed wit two rows of perforations 7 which extend along .their length and are arranged in the pipes 2, in the relation shown inFi 3, wherem the rows are disposed inan arc o alpproximately of 90, the (perforations being lsposed to discharge an direct the in paths at right angles to one another, as illustrated by Figi 3.

designates the drainage pipe provided Ywith valve b, which leads from 'vat A.

In Fig. 1, of the drawings I have depicted a convenient mixing device which conslsts of a a building or structure, platform 'or Hoor E, being arranged above the top of vat A, and having a large vat F, thereon. Vat F, is provided with discharge trou h or spout G, w -ch communicates therewit and extends through wall C, to overlie-the top of boiling vat A, and discharge thereinto.

In connection With the means for filling the barrels with the concentrated lime and sulfur solution, which means embodies a horizontal pipe 8, extending through wall C,y and on the interior of vat A. This of vat A, is equipped with elbow 12, into which is fitted a short section of pipe 13, having a horizontal disposition connected to an annular elbow 14, having its outer end connected to outletpipe 15, the latter being capable of movemen't in a vertical semi-rotary plane to the positions shown in full and dotted lines in Fig. 1, and positions intermediate the same. `It will be readily understood that as the level of the solution -in vat A, is lowered due to the discharge of the same,

vat A, I employ' pipe at its end on the inside '.70 platform E, which is secured to the wall C, ofV

pipe 15, is lowered to constantly maintain its open upper orouterend directly beneath the level of the solution, so that the solution may at all times have access to such pipe.

9, designates a valve on the end of pipe 8, which controls the discharge of the solution through such pipe, there being a flexible hose 10, and turn i e nozzle 11', on the free end of hose 10, whlcii is inserted in the bung hole of the barrel in filling the latter. A

In operation the lime in proper pro ortion in water in F and the su fur in proper proportion is added during the time the lime is slakin the vmixture thus formed `-with the require amount of water is then allowed to dlscharge through s out into vat A. Inasmuch as vat A, as dlepicted is of annular form the cross pi es' 2, are so arconcentrated solution by the use o steam which uniformly agitates and boils the material from the bottom up.

What I claim isz- 1. An apparatus of the type set forth, comprising a vat, a steam supply pi e, a transverse .feed pipe connected to the ower end of said supply pipe, said feed ipe decreasing in diameter towards its en s, being of greatest diameter at its point-of connection with the supply pipe and of least diameter at its ends, and a series of cross pipes perforated on their under sides and having their ends terminating at points adjacent the inner circumference of the vat.

2. In an apparatus of the type set forth, a vat, a steam supply (pipe leadlng into said vat, a transverse fee pipe decreasing in diameter as its ends are approached, secured to the said sup ly pipe at a point adjacent the. bottom of t e vat, and a multiplicity of cross pipes having closed ends and perforations on their under sides secured to said feed pipe on o posite sides thereof, and at regular intervas throughout the length of the feed pipe.

3, An apparatus of the type set forth,

com rising a vat, a steam supply pipe lead-I ing t ereinto, a transverse feed p1 e connected to the steam pipe and compose of a series of sections which decrease 1n diameter towards the ends of the said feed pipe, couplings for connecting said sections, a multiplicity of cross pipes arranged on opposite sides of the feed pipe throughout the length of the feed ipe connected to said couplings and each ormed with pairs of apertures throughout their length, ther apertures of each pair being disposed so as to discharge the steam therefrom in paths at right angles to one another, a horizontal pipe leading into the vat adjacent its bottom and a pipe connected to the inner end o said horizontal pipe and having movement in a vertical rotary plane. ,K

4. An apparatus of the ty e set forth, comprising a vat, a mixin tan located at a point above said vat and aving a discharge spout which extends over said tank and disc arges thereinto, means for feeding steam against the lbottom of the tank at spaced points throuhout the area thereof, and meansto ena le thevat contents to be removed by taking the same from the level thereof, said last named means bein movable to enable the same to continuallybe lowere as the level of the vat contents are lowere l5. A n apparatus for boiling lime and sulfur composed of a vat, a main steam supply pipe for said vat, a series of perforated pi es extending throughout the area, of the ottom of the vat, and a pi e having taperin portions connecting sai series of pipes wit said main steam supply pipe whereby the steam egressing from said perforated piples will be discharged at the same pressure t roughout the length of each.

6. An ap aratus for boiling lime and sulfur composed o a vat, a main steam sup ly pipe, a transverse feed pipe connected to t e inner` end of said main steam supply pi e, a series of perforated cross pipes,connec ed to said transverse feed pipe, said transverse feed pipe being forme to discharge steam at an equal ressure to each of said cross pipes.A

7. apparatus for boiling lime and sulfur composed o a vat, a main steam supply pipe, a series of perforated pipes arranged at spaced intervals throughout the area of the vat, and means connected to said perforated pipes and to said main supply pipe whereby the-steam will be fed to the perforated pipes at an equal pressure.

In testimony whereof I have signed my name to the specification in the presence of ltwo subscribing witnesses.
